DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred embodiments of the present invention will be described in detail herein below with reference to the accompanying drawings. In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings.

In the following description, specific details such as types of events, information necessary for expressing an agent, and so on are provided for a better understanding of the present invention. Those skilled in the art will appreciate that the present invention can be easily implemented through various modifications without the specific details.

FIG. 1 illustrates a structure of a wireless terminal in accordance with an embodiment of the present invention.

Referring to FIG. 1, a radio communicator 21 performs a wireless communication function of the wireless terminal. The radio communicator 21 includes an RF transmitter for up converting and amplifying a frequency of a signal to be transmitted, an RF receiver for low noise amplifying a received signal and down converting a frequency of the received signal, and so on.

A key input unit 25 is provided with keys for inputting number and letter information and function keys for setting various functions. Moreover, the key input unit 25 is provided with keys for controlling a character agent on an event-by-event basis in accordance with an embodiment of the present invention.

A memory 23 can be configured by program and data memories. The program memory stores programs for processing a call of the wireless terminal and programs for controlling agent expression for events occurring in accordance with an embodiment of the present invention. The data memory performs a function for temporarily storing data generated while the programs are executed. Moreover, the data memory is provided with a character memory for storing character images for agent expression in accordance with an embodiment of the present invention. The character memory can operate with a file system, and can have an index of a character-by-character memory (or file system). The character memory can be configured in various forms for enabling operations, facial expressions, and object representations of character components. Character information can be stored in the character memory according to forms capable of performing agent expression.

The controller 100 performs a function for controlling the overall operation of the wireless terminal. Moreover, the controller 100 is provided with a modulator-demodulator (MODEM) for modulating/demodulating a signal and a coder-decoder (CODEC) for coding/decoding a signal, thereby performing a function for coding and modulating a signal to be transmitted and a function for demodulating and decoding a received signal. Here, the controller 100 may be a mobile station modem (MSM) chip. A data processor is independently configured to separate the MODEM and the CODEC from the controller 100. The data processor can be placed between the radio communicator 21 and the controller 100. Moreover, the controller 100 controls an operation of communication mode, camera mode, and broadcasting reception mode in response to the user's mode selection.

In accordance with an embodiment of the present invention, the controller 100 collects an event according to the operation of the wireless terminal, controls an agent according to the collected event, and expresses a result of processing and a state of the event using an agent. Here, the agent expression can be displayed after an associated character is selected from the memory 23.

At the time of the user's camera mode selection, a camera 35 is started by the controller 100 and generates an image capture signal in the camera mode. An image processor 37 scales the image capture signal from the camera 35 according to a size of a display unit 27 in the camera mode, and encodes and stores the image capture signal in storage mode according to a set scheme. In mode for reproducing received or stored image data, the image processor 37 performs a function for decoding encoded image data. In the camera mode, the image processor 37 controls the display unit 27 to display an image signal.

In the broadcasting reception mode, a tuner 31 selects and receives a broadcast signal of a channel set in the controller 100. A broadcast processor 33 demodulates and decodes the broadcast signal of the selected channel, and outputs the demodulated and decoded image signal to the display unit 27. An audio signal is output from an audio processor 29. Here, the broadcast signal is a digital broadcast signal, and may be a satellite broadcast signal or a terrestrial broadcast signal.

Under control of the controller 100, the display unit 27 can display menus according to the operation of the wireless terminal. When an event occurs, the display unit 27 displays an associated event state using a character under control of a selected agent mapped to the event. Moreover, the display unit 27 displays an image signal output from the image processor 37 or the broadcast processor 33 in the camera mode or the broadcasting reception mode.

Under the control of the controller 100, the audio processor 29 processes an audio signal generated in the communication mode. Under the control of the image processor 37, the audio processor 29 processes an audio signal generated during an image capture operation in the camera mode. The audio processor 29 processes a broadcast audio signal received under the control of the broadcast processor 33 in the broadcasting reception mode.

A structure for processing the camera signal and/or broadcast signal can be omitted from the wireless terminal with the above-described structure. In this case, a character agent function for an event can be performed in accordance with an embodiment of the present invention. In the following description, it is assumed that the character is an avatar. Accordingly, character agent control for an event of the wireless terminal will be described as avatar agent control, but can be equally applied for all images as well as the avatar.

The present invention provides a user of the wireless terminal with a useful function through a character interface on the basis of an artificial agent system, and can bring up a character using the wireless terminal. FIG. 2 illustrates a structure of an agent system with a character agent function in accordance with an embodiment of the present invention.

Referring to FIG. 2, the wireless terminal is provided with a character agent system 50 and a character interface 60 in accordance with an embodiment of the present invention. The character agent system 50 is configured by an event processing system 52 and an agent module 54. Here, the agent module 54 serves as a module for providing various useful functions, and has a structure in which a function is easily added and deleted because the functions are independent. That is, the agent module is obtained by grouping a call related agent, system related agent, schedule related agent, message related agent, application related agent, character growth related agent, and so on as illustrated in FIG. 2. The agent module may include a camera related agent, digital broadcast related agent, global positioning system (GPS) related agent, and so on in addition to the above-described agents. As described above, the grouped agents are separated and modularized according to a detailed function. When the agent system 50 detects various events occurring in the wireless terminal and transfers the occurred events to necessary functions, many situations are synthesized in an associated function and the system is notified of the presence of an associated function operation. The agent system 50 operates functions suitable for the current situation according to the priority. In this case, the agent system 50 receives feedback information through the character interface 60 such that an associated function can be operated in various schemes according to the user's preference.

The character quotient is updated according to various events occurring in the wireless terminal, an agent function, and the user's feedback. Also, many applications capable of using the character quotient affect the character quotient. As the character quotient is varied, a character is varied. As the time is elapsed, the appearance in which the character is brought up can be viewed. Here, the character growth and variation correspond to character growth. In accordance with an embodiment of the present invention, a function for bringing up a character on the basis of an artificial intelligence (Al) agent is introduced into the wireless terminal, such that it can provide a character agent system which is different from a terminal for expressing the conventional character growth (e.g., Tamagotchi) and character function.

In accordance with the embodiment of the present invention, the above-described character agent system provides use convenience and pleasure to wireless terminal users. A function for providing the use convenience and pleasure in the wireless terminal is referred to as a use case or case. This will be described in more detail.

In accordance with the embodiment of the present invention, the character agent system includes a use case diagram and a package diagram. According to the use case diagram, an event occurring in the character agent system is transferred to cases. The most suitable case is only displayed through a UI. Then, the wireless terminal user generates feedback information for the system through selection for recommendations shown through a character. FIG. 3 illustrates a case diagram of the agent system with the character agent function in accordance with an embodiment of the present invention.

Moreover, the package diagram is a diagram in which the character agent system is divided into three parts of an event collector, an agent controller, and an agent UI expression part or four parts of an event collector, an event delivery server, an agent controller, and an agent UI expression part. Here, the event collector collects events of the wireless terminal for operating a character agent. The event delivery server delivers the collected events to the agent controller. The agent controller analyzes the delivered events, refers to its data, and controls the agent UI expression part to express a character. At this time, the event delivery server performs a function for delivering the events collected by the event collector to the agent controller, and performs a function for receiving, from the character agent system, an event incapable of being received through the event collector and delivering the received event to the agent controller. Accordingly, the event delivery server can be omitted in case of the character agent system for collecting all events through the event collector. The package diagram of the character agent system is illustrated in FIG. 4.

Here, the character may be a human, animal, or plant character. In the following description of the present invention, it is assumed that the character is an avatar.

FIG. 3 illustrates an example in which the agent system of the wireless terminal analyzes occurred events and controls and displays associated avatar UIs in accordance with an embodiment of the present invention.

Referring to FIG. 3, the event can arbitrarily occur in a program of the wireless terminal and can occur in a case and avatar UI. When the event occurs, specialists check a case for the occurred event and express the occurred event using a suitable avatar UI when the event is suitable for an associated case as a result of the checking. That is, when the event occurs, specialists mapped to an identifier (ID) of the occurred event analyze a case for the occurred event. A specialist with the closest relation to the event is selected, and an avatar UI of the selected specialist is expressed.

FIG. 4 illustrates a structure for expressing events occurring in the wireless terminal with a character agent system using an agent function in accordance with an embodiment of the present invention. The structure may be an internal structure of the controller 100.

Referring to FIG. 4, an event collector 110 performs a function for collecting events occurring in the wireless terminal. Here, the events include all events of the wireless terminal such as a communication event of the wireless terminal, an event independently occurring in the wireless terminal, an event occurring according to the user's request, and an event occurring when a multimedia function of the wireless terminal is performed. That is, the events collected by the event collector 110 are events defined in the wireless terminal. The event collector 110 extracts information necessary for an occurred event when the event occurs, generates an event message, and outputs the event message to the event delivery server 120.

The event delivery server 120 performs a function for delivering the event message received from the event collector 110 to an associated client. In accordance with an embodiment of the present invention, it is assumed that the event message is delivered only to the agent controller 130. When a different component makes an event message delivery request, the event message can be delivered to the different component. Moreover, the event delivery server 120 receives user-defined events undefined in the wireless terminal as well as the events received from the event collector 100 and delivers the received events to the agent controller 130. Here, the above-described events are referred to as the application events. The application events may occur in games, other application programs, and web service programs.

When receiving an event message from the event delivery server 120, the agent controller 130 stores the received event message in an internal buffer, and analyzes the event message to set a UI such that an associated character agent can be expressed. Here, the event delivered from the event delivery server 120 may be events of the wireless terminal (e.g., events received from the event collector 100) and application events. In the following, a description is focused on the agent expression for an event received from the event collector 110. The agent controller 130 is provided with a plurality of specialists. The agent controller 130 controls these specialists, selects a specialist mapped to an occurred event, and performs an agent control function. When an event is received, the agent controller 130 notifies suitable specialists of event occurrence according to the received event, and sends a UI request to the agent UI expression part 140 such that agent expression of the finally selected specialist can be displayed. In response to feedback information of the user received from the agent UI expression part 140, the user feedback information for an associated event is processed.

The agent UI expression part 140 displays the character expression for an associated event according to agent UI information output from the agent controller 130. At this time, the agent UI expression part 140 manages a plurality of avatars to be displayed on the display unit 27. The agent controller 130 performs a control operation such that an avatar mapped to requested UI information can be displayed. When the user generates the feedback information in a state in which the avatar has been displayed according to the occurred event, the agent UI expression part 140 sends the received feedback information to the agent controller 130.

When only the events of the wireless terminal received from the event collector 110 are processed in the structure of FIG. 4, the event delivery server 120 can be omitted as described above.

When the event occurs, the event collector 110 extracts information necessary for an event as shown in Table 1 and generates an event message with suitable parameters. Then, the agent controller 130 suitably changes the received event message, stores the changed event message in the internal buffer, and controls an agent according to the event message and parameters. TABLE 1 Event Type Occurrence Time Parameter 1 — Parameter n

For example, when an event of “AP_CONTAC_ADD” occurs in a procedure for processing the event message, the event collector 110 generates an event message of (AP_SMS_SEND, 2004-09-06 14:00, 65) as shown in Table 2. In the event message, “65” means that an ID of No. 65 has been generated in a message database. When the agent controller 130 receives the event message as shown in Table 2, the event is “AP_SMD_SEND”. Accordingly, an ID is retrieved from the message database. When the ID of No. 65 is mapped to a name of “James bond” and a phone number of “016-432-3792”, the agent controller 130 stores the event message in the internal buffer as shown in Table 3. TABLE 2 Event Type Occurrence Time Parameter 1 (ID) AP_SMS_SEND 2004-09-06 14:00 65

TABLE 3 Event Type Occurrence Time Parameter 1 Parameter 1 (ID) AP_SMS_SEND 2004-09-06 14:00 James bond 016-432-3792

Here, the internal buffer of the agent controller 130 is referred to as the blackboard.

Now, the operation of the event collector 110, the event delivery server 120, the agent controller 130, and the agent UI expression part 14 will be described in more detail.

FIG. 5 illustrates a structure of the event collector 110 of FIG. 4. The event collector 110 performs a function for collecting all events occurring in the wireless terminal. The collected events are processed in the agent controller 130 to be described below, such that an avatar UI can be displayed.

Referring to FIG. 5, the event collector 110 is configured by a plurality of event detectors 222 to 236 and an event collection manager 21 for collecting events detected from the event detectors 222 to 236, generating an event message, and delivering the generate event message to the event delivery server 120.

The system event detector 222 detects the occurrence of a system event according to a state of a battery, and a state of the wireless terminal associated with a communication environment (or radio wave problem), a memory, etc. The address book event detector 224 detects a change of an address book according to the user's manipulation. The setup event detector 226 detects an event for changing setup information of the wireless terminal such as a language and time. The message event detector 228 detects the occurrence of a message event such as a short message service (SMS), a multimedia messaging service (MMS), an e-mail, and so on. The schedule change event detector 230 detects schedule and alarm events such as schedule, reservation, alarm, and so on. The camera event detector 232 detects an event associated with the operation of the camera when the camera is mounted to the wireless terminal. The broadcast event detector 234 detects an event associated with broadcasting reception in case of the wireless terminal provided with a broadcast receiver (e.g., a digital broadcast receiver (for digital multimedia broadcasting (DMB), digital video broadcasting (DVB), or etc.), a general broadcast receiver, or etc.). Here, the broadcasting can include digital broadcasting such as digital terrestrial and satellite broadcasting and the conventional analog broadcasting. The call event detector 236 detects an event associated with a call of the wireless terminal (e.g., an incoming call, outgoing call, missed call, or rejection).

The events detected in the event detectors 222 to 236 are applied to an event collection manager 210. The event collection manager 210 identifies the received events, and generates an event message configured by an event type, occurrence time, and ID. In this case, the event message may be one of messages with the format as shown in Table 1. The message is applied to the event delivery server 120.

As described above, the event collector 110 is configured by the plurality of event detectors 222 to 236, and the event collection manger 210 for collecting events detected by the detectors 222 to 236 and generating an event message such that the agent controller 130 can perform a control operation. An example in which the eight event detectors have been configured has been illustrated in accordance with an embodiment of the present invention, but an increased number of event detectors can be provided. The camera event detector 232 and/or the broadcast event detector 234 can be provided or omitted according to a mounted device.

FIG. 6 illustrates a structure of the event delivery server 120 of FIG. 4. The event delivery server 120 delivers a received event to a desired client.

Referring to FIG. 6, the event delivery server 120 is configured by a plurality of client connectors 252 to 258 and an event delivery processor 250, connected to the client connectors 252 to 258, for receiving and delivering an event message. A device desiring to receive the event message (e.g., the agent controller 130 as illustrated in FIG. 6) must send an event message delivery request to the event delivery server 120. In an embodiment of the present invention, it is assumed that the agent controller 130 makes an event message delivery request as illustrated in FIG. 6.

In FIG. 6, the event collector 110 is connected to the first client connector 252. The client connector 252 performs a function for delivering the event message collected by the event collector 110 to the event delivery processor 250. In this case, an event message generated from the event collector 110 is information about an event occurring in the wireless terminal as described above.

The agent controller 130 is connected to the second client connector 254. In this case, the agent controller 130 sends an event message delivery request to the event delivery server 120 to receive an event message generated from the event collector 110. The second client connector 254 sends the event message delivery request to the event delivery processor 250. The event delivery processor 250 registers the event message delivery request and then prepares to send the received event message to the agent controller 130. In this case, when the first client connector 252 or the n-th client connector 259 receives the event message, the event delivery processor 250 delivers the received event message to the second client connector 254 and the second client connector 254 sends the received event message to the agent controller 130. That is, the event delivery server 120 performs a function for delivering the received event message to the agent controller 130 making the event message delivery request.

The n-th client connector 258 may be a plurality of connectors. The n-th client connector 258 performs a function for receiving application events except the events generated from the event collector 110. In this case, the events capable of being received by the n-th client connector 258 serve as events undefined in the wireless terminal as described above, and may be events generated by games, other application programs, and web service programs.

As described above, the event delivery server 120 performs a function for receiving all events occurring in the wireless terminal and delivering the received events to the agent controller 130 making an event delivery request. In an embodiment of the present invention, it is assumed that only the agent controller 130 makes an event delivery request. However, when a different agent controller is further provided and an event delivery request is made, the agent delivery server 120 can analyze a received message and distribute or deliver the received event message to an associated agent controller.

FIG. 7 illustrates a structure of the agent controller 130 of FIG. 4. The agent controller 130 manages specialists, sets a UI ID for the finally selected specialist, and provides an indication of the set UI ID to the agent UI expression part 140. The agent controller 130 operates according to the user's feedback information based on a displayed avatar UI.

Referring to FIG. 7, the agent controller 130 stores an event message delivered from the event delivery server 120 in an internal buffer (or blackboard) 330, sets a UI ID from a specialist mapped to the event, and outputs the set UI ID to the agent UI expression part 140. When the user generates feedback information according to an avatar agent function displayed by the agent UI expression part 140, the agent UI expression part 140 receives the feedback information and performs an agent control operation according to the user feedback information. To perform the above-described function, the agent controller 130 is provided with a plurality of specialists 322 to 328 with agent UI IDs, the blackboard 330 for storing information of event messages, a supervisor 350 for selecting at least one specialist when an occurred event is associated with a plurality of specialists, an avatar quotient memory 340 for managing an avatar quotient according to the occurred event, a timer processor 370 for enabling the specialists 322 to 328 to perform a specific action at a specific time, a specialist manager 310 for selecting associated specialists from a list of event-by-event specialists at the time of event occurrence and controlling an agent according to an event, and so on.

After a description of the components of the agent controller 130, the operation of the agent controller 130 will be described. The agent controller 130 is provided with an agent engine serving as a core part for operating a character agent system. Here, the agent engine is a blackboard 330, a timer processor 370, and a supervisor 350, and includes codes for organically connecting the blackboard 330, the timer processor 370, and the supervisor 350 to the specialists 322 to 328.

First, the specialists 322 to 328 are specialists for addressing problems and have specialty for defined parts. Each of the specialists 322 to 328 refers to the blackboard 330 to find out a solution and makes efforts such that it can be finally selected.

The specialists 322 to 328 are substantial task processors operated by the agent engine. One specialist processes one case or use case. Accordingly, when 50 cases are processed, 50 specialists are required. Because an additional specialist exists to maintain the system, the number of specialists needs to be more than the number of cases to be processed. Each of the specialists 322 to 328 is provided with an algorithm suitable for a task to be processed. Codes must be implemented with a predetermined standard such that they are called and processed by the agent engine. In an embodiment of the present invention, it is assumed that a specialist interface uses an MSspecialist interface as shown in Table 4. The specialists 322 to 328 access the blackboard 330 and read or write information. The specialists 322 to 328 can set a desired operation time using the timer processor and can change the set time. TABLE 4 CBlackboard −iDatabase: RDbDatabase +iAgentAlarm: CAgentAlarm* +static NewL ( ): *CBlackboard +GetDatabase ( ): RDbDatabase& +Insert (TAPEvent) +Insert (TAPEvent. TInt) +Insert (TAPEvent. TInt. TDesC16&) +Insert (TSpecialistId. TUserFeedback) +GetAgentAlarm ( ): CAgentAlarm* +RemoveFutureDataL ( )

Table 4 shows a specialist interface, and defines a function to be implemented by the specialists 322 to 328. When an event occurs, an operation form of an associated specialist is determined through DetermineActivated( ) of Table 4. When an operation time is reached, GetUIInfo( ) is called by the engine. After information necessary for UI expression is provided, action according to the user's selection is performed in ActvateL( ).

In an embodiment of the present invention, the specialists 322 to 328 must be provided which are more than or equal to the number of cases or use cases. Table 5 shows an example of cases in accordance with an embodiment of the present invention.

Second, the blackboard 330 is a working environment or information space for communication between the specialists 322 to 328. Basically, the specialists 322 to 328 can use or record information if needed. Advantages of a pattern of the blackboard 330 are as follows. First, many specialists 322 to 328 of different types can be easily integrated. Second, the specialists 322 to 328 can be independently modularized and developed because they seldom affect each other. Third, flexibility is provided for many variations (such as a change of a specialist algorithm or an addition of a new specialist).

As described above, the blackboard 330 serves a working environment or information space and supports a convenient and flexible information search. This can be designed in a tuple space adopted in a relational database or Linda, Jini and Java object spaces.

The specialists 322 to 328 require past records. For example, a specialist for automatically recommending a phone call transmission when a phone call transmission pattern is detected at a specific time will be described. A recommendation time can be computed when many past phone call transmissions are identified. In a state in which an event of the phone call transmission is recorded, the event can be retrieved from a database called the blackboard 330 if needed. In the wireless terminal with the character agent function, all the specialists 322 to 328 share the single blackboard 330. Of course, the agent engine also uses the blackboard 330. The agent engine must record an event occurring in the blackboard 330 and must record feedback information of the user. Each of the specialists 322 to 328 refers to the blackboard 330 to determine its own action and records specific information to the blackboard 330. Because the blackboard 330 is shared, all records recorded by different specialists can be referred to. Table 6 shows the blackboard 330. TABLE 6 <<abstract>> Mspecialist #ConstructL (CBlackboard*. MEventSender*) +ReleaseL ( ) +GetInfo ( ): TInfo +DetermineActivated (TAPEvent): TAnswer +DetermineActivated (aAlarmId: TUint32. aData: const TDesC16&): TAnswer +Activated (aFeedback: TUserFeedback. AData: const TUint8*) +GetUIInfo (TUIId&. TIndex&. TTokens&) +HandleTimeChangedL (aError: TInt)

The blackboard 330 can record event information through Insert( ), and provides an additional Insert( ) such that additional information accompanying the event can be stored. Insert( ) in which IDs of the specialists 322 to 328 are used as the first factor is a function for recording feedback information of the user. The specialists 322 to 328 can access and search the blackboard 330 through GetDatabase( ).

Third, the timer processor 370 will be described. The timer processor 370 performs a function for operating the specialists 322 to 328. The specialists 322 to 328 are woke up by events occurring in the agent system, but require a timer to take a specific action at a specific time. A determination time of the specialists 322 to 328 may be different from an action time, i.e., a time when a character UI is expressed and viewed by the user. That is, a certain specialist may completely depend on the timer processor 370. For example, the SCH06 specialist (for a case for recommending that the user check a total schedule at a designated time) in cases shown in Table 5 is a specialist to be periodically executed everyday, and is a specialist completely depending on the timer processor 370. However, many specialists using the timer processor 370 require events occurring in the wireless terminal. When the event occurs, the specialist determines if a character UI will be expressed. When the specialist determines that the character UI is suitable to be displayed at a specific day and time (or month, day, and time), or again makes a determination after a specific time is elapsed, it calls a determination function using the timer processor 370. In an embodiment of the present invention, the wireless terminal with the character agent system uses one timer processor 370 to reduce system load as illustrated in FIG. 7. A request for timing (year, month, day, hour, minute, and second) for waking up each specialist is stored in the blackboard 330. The timer processor 370 performs processing for the time mapped to the earliest request of stored requests. When the request time is reached and then an alarm is operated, an associated request is deleted from the blackboard 330. Then, a request for the earliest alarm is set in the timer processor 370.

The specialist is responsible for using the timer processor 370. That is, the specialists 322 to 328 can set a time in the timer processor 370. When the setup time is unnecessary, a set time must be deleted or changed. When the set time is reached, the timer processor 370 is operated, such that the specialist setting the timer calls the second DetermineActivated( ) from the specialist interface as shown in Table 4. The remaining process is performed in the same order as the operation order for other events.

The time change phenomenon is an element making the timer processor 370 complex. It is assumed that a timer has been set such that a certain specialist is operated after one week and that the user has changed the date of the wireless terminal to that before one year. When the timer processor 370 does not process a time change, it will be operated after one year and one week. The blackboard 330 accumulates records of a later date than the changed date. The wireless terminal with the character agent system can detect a changed time, but cannot detect a time before the change. The engine deletes future records according to a time change incapable of being predicted and simultaneously notifies all the specialists 322 to 328 that a time change has been made through a specialist function of HandleTimeChanged( ). The specialists 322 to 328 cope with the time change. Table 7 shows the action of the specialists 322 to 328 according to the time change. TABLE 7 Class No. No. Function APP00 29 (1) If a date is changed to one week before the set timer date, a timer is maintained. (2) Otherwise, the timer is deleted.

The operation of the timer processor 370 will be described. Among the specialists 322 to 328, specialists requiring or not requiring a timer are present. In this case, the specialists requiring the timer set, change, or delete a timer in the timer processor 370 as described above. When the specialist sets a timer in the timer processor 370, the timer processor 370 notifies the specialist manager 310 that the timer has been set. The specialist manager 310 operates a specialist setting the timer and performs a control operation such that a UI of an associated specialist can be expressed within a set time.

Fourth, the supervisor 350 synthetically determines user preference information and a current situation associated with the blackboard 330 and its own specialists 322 to 328 and selects a specialist for expression. At this time, the supervisor 350 can select the most suitable specialist from the specialists when selecting a specialist for expressing the character UI. When the number of specialists for expressing the character UI is multiple, all specialists can be displayed.

The operation of the supervisor 350 when the specialists express the character UI as in the latter will be described.

When an event occurs, the engine is notified of an action pattern through a determination function of a specialist. The action pattern is divided into three patterns of “No Action”, “Action for displaying a UI now”, and “Action for deletion in a queue during waiting for expression” or “Action for hiding when a UI is currently being expressed”. Many specialists may simultaneously notify the engine of the action pattern of “Action for displaying a UI now”. In this case, the engine needs to adjust the specialists in a competition relation. Because the specialist cannot know the presence of a different specialist, it only performs an expression or hiding operation, etc. Accordingly, when specialists for expressing a character UI are delivered to the supervisor 350, the supervisor 350 arranges specialists desiring to express a character in the following algorithm.

An algorithm of the supervisor 350 has three rules. First, a basically designated priority is set to be highest. Second, the user preference is reflected. Third, all specialists must be able to express a character UI (i.e., the specialist must not be hungry).

The algorithm of the supervisor 350 will be described. Assuming that a basically designated priority is p1 (p1>0) and the user preference for an associated specialist is p2, a priority for expressing a character UI of the specialist (hereinafter, referred to as a UI expression priority) is computed as follows. ${p = {\left( {1/\left( {{p\quad 1} + 1} \right)} \right) \star {p\quad 2}}},{{{where}\quad p\quad 2} = {1 - {\text{(}\left( {{{r(0)} \star {f(0)}} + \left( {{{r(1)} \star {f(1)}} + \ldots + {\left( {{r\left( {k - 1} \right)} \star {f\left( {k - 1} \right)}} \right)/\left( {{g(0)} + {g(1)} + \ldots + {g\left( {k + 1} \right)}} \right)}} \right)} \right)}}},\quad{k\quad{can}\quad{be}\quad{set}\quad{to}\quad 14},\begin{matrix} {{r(i)} = {{xi}/\left( {{xi} + {yi}} \right)}} & {{{{if}\quad{xi}} + {yi}} > 0} \\ {= 0} & {{{{{if}\quad{xi}} + {yi}} = 0},} \\ {{{f(i)} = {1/\left( {1 + {2\quad{\log_{k}\left( {i + 1} \right)}}} \right)}},} & \quad \\ {{g(i)} = 1} & {{{{if}\quad{xi}} + {yi}} > 0} \\ {= 0} & {{{{{if}\quad{xi}} + {yi}} = 0},} \end{matrix}$

r(i)=a ratio relating to a negative opinion of a user on the i-th day before the current day,

f(i)=a reduction factor of a negative opinion of a user on the i-th day before the current day,

g(i)=the number of acceptances or rejections on the i-th day before the current day,

xi=the number of times when the user rejected the specialist on the i-th day before the current day, and

yi=the number of times when the user accepted the specialist on the i-th day before the current day.

The reason why k is set to 14 will be described. A rejection level in which the user rejected the specialist 14 days ago is computed in a ratio of r(i). When the user completely rejected the specialist 14 days ago, the rejection ratio is 1. As a period of time has been elapsed, r(13)=1/(1=2)=0.33. If the user desires to change a slope of the curve according to time, k needs to be changed. Table 8 shows an example of algorithm computation of the supervisor 350 when it is assumed that k=14. FIG. 8A illustrates an example of a rejection related curve in the algorithm of the supervisor 350 in accordance with an embodiment of the present invention. FIG. 8B illustrates an example of computing a reduction factor f of a negative opinion in the algorithm of the supervisor 350. FIG. 8C illustrates an example of a corrected rejection related curve in the algorithm of the supervisor 350. TABLE 8 Limited time No. Class No. Priority (minutes) 0 MSG06 0 10 1 SYS00 2 30 2 CL00 0 10 3 CL01 0 10 4 CM00 1 10 5 CM01 1 10 6 CM02 1 10 7 CM03 2 No 8 CM04 2 No 9 CL02 1 10 10 CM05 2 No 11 CL03 2 30 12 MSG00 2 30 13 CL04 2 No 14 MSG01 2 No 15 MSG02 1 10 16 MSG03 2 30 27 SCH06 1 10 28 SCH07 1 10 29 APP00 1 10 30 APP01 1 10 31 SYS02 0 10 32 SYS03 0 10 33 TD00 1 10 34 TD01 1 10 35 SYS04 0 10 36 AVA00 2 30 37 SYS05 0 10 38 APP02 1 10 39 CM06 2 No 40 CM07 2 No 41 APP03 1 10 42 SYS06 2 No 43 SYS07 2 No

An example of a rejection related curve illustrated in FIG. 8A expresses the ‘r’ value in the algorithm computation of the supervisor 350 shown in Table 8 and shows the number of rejections on a date-by-date basis. FIG. 8B illustrates a curve indicating a level in which the user preference is reflected on the date-by-date basis in the ‘f’ computation of the algorithm of the supervisor 350. It can be found that a stronger user preference is reflected on an earlier date. The rejection related curve corrected in the algorithm of the supervisor 350 in FIG. 8C indicates the number of rejections computed along with the user preference reflected on the date-by-date basis. A final computation result is reproduced from these values. In an above example, a ratio in which the user prefers an associated specialist is computed as 0.79012323. On the basis of this ratio value and a basically designated priority of an associated specialist, a final UI expression priority is computed.

The supervisor 250 sends, to the engine (or specialist manager), a list of specialists arranged according to computed UI expression priorities. At this time, the supervisor 350 can exclude a specialist with an excessively low UI expression priority. Even though 10 specialists have been selected as candidates, the number of specialists for expressing an actual character UI may be less than 10. Even though a specialist with the excessively low UI expression priority is excluded, the specialist excluded for a long time must have an opportunity to express a character UI according to Rule 3 of the algorithm of the supervisor 350.

FIG. 9 illustrates a priority queue for storing specialists arranged according to UI expression priorities set by computation of the supervisor 350. As illustrated in FIG. 9, all specialists are assigned one of the following three UI expression priorities, respectively. First, a specialist of the 0^(th) priority is a specialist for expressing a character UI even when the wireless terminal is being used. A specialist of the 1^(st) priority is a specialist appearing even when the wireless terminal is being used and a specialist waiting while another specialist is expressing a character list or in a waiting state. A specialist of the 2^(nd) priority waits without expressing any character UI while the wireless terminal is being used. Table 9 is a basic priority allocation table for the specialists 322 to 328. TABLE 9 r(i) = Rejection/ f(i) = 1/(1 + 2 Sum of i Acceptance Rejection (Acceptance + Rejection) log_(k) (i + 1)) r(i) * f(i) r(i) * f(i) 13 1 2 0.666666667 0.333333333 0.222222 2.30864442 12 0 2 1 0.339692658 0.339693 11 0 1 1 0.346839558 0.34684 Sum of g(i) 10 1 0 0 0.354957811 0 11 9 3 2 0.4 0.364297963 0.145719 8 4 0 0 0.375212184 0 7 5 1 0.166666667 0.388214249 0.064702 6 3 2 0.4 0.404089233 0.161636 5 0 0 0 0.424110082 0 4 0 0 0 0.450509977 0 3 5 1 0.166666667 0.48766259 0.081277 2 10 2 0.166666667 0.54567897 0.090946 1 0 3 1 0.655609132 0.655609 P2 0 4 1 0.2 1 0.2 0.79012323

When the wireless terminal does not express a character UI, the priority queue of FIG. 9 is empty. In case of Priority 0, a new specialist is added before the priority queue. Specialists of UI Expression Priorities 1 and 2 are added after a specialist waiting in Priority 0. Accordingly, the specialists of UI Expression Priorities 1 and 2 do not affect the character UI expression of the current specialist. However, the specialist of UI Expression Priority 0 stops the character UI currently being expressed and expresses its own character UI. Accordingly, a new specialist of Priority 0 can hide the character UI currently being expressed and express its own character UI. The specialist of the 1^(st) priority can hide the character UI expression of the specialist of the 2^(nd) priority and express its own character UI. When an identical UI is currently being expressed or the waiting state is entered, the character UIs of the 1^(st) and 2^(nd) priorities must wait their turns for character UI expression. When the user's input is present or no input is present for a predetermined time, the character UI is automatically deleted from the priority queue. At this time, the first item of the priority queue with the structure of FIG. 9 is deleted and a character UI of the next specialist is expressed. UI Expression Priority 2 must not be expressed in a state in which the wireless terminal is being used. Using a method operating after a predetermined time is elapsed when an inactivation related function provided in the wireless terminal is used or the user presses a key, a character UI must be expressed after an inactivation time of the system is detected.

The specialists have the limited time in which the character UI is expressed along with the UI expression priority as shown in Table 9. After the limited time is elapsed, the character UI is not meaningful. For example, the effect of the recommendation for a specific operation at a specific time is lost after a predetermined time is elapsed.

After the basically designated priority and the user preference are computed, a specialist of the highest priority is selected and a character UI of the selected specialist can be expressed. This method corresponds to the former of the methods for selecting a specialist.

Fifth, the avatar quotient memory 340 performs a function for containing an avatar quotient changed according to an occurred event and the user's action based on the occurred event. In accordance with an embodiment of the present invention, the wireless terminal provides its user with a useful function through an avatar interface based on the AI agent system and can bring up an avatar through use of the wireless terminal. The agent system detects various events occurring in the wireless terminal and delivers the detected events to the respective functions. Then, many situations are synthetically considered in an associated function and the system is notified of the presence of an associated function operation. The agent controller 130 selects one or more specialists most suitable for the current situation and prepares an operation. Feedback information is received from the user through an avatar interface such that an associated function can be operated in various ways according to the user preference.

An internal quotient of an avatar is varied according to various event and agent functions occurring in the wireless terminal and the feedback information of the user. Also, many application events capable of using the avatar quotient affect the avatar quotient. As the internal quotient is varied, an avatar interface is varied. As a period of time is elapsed, the appearance in which the avatar is brought up is viewed. This is a growth concept of the avatar. In accordance with an embodiment of the present invention, the avatar growth is introduced into the wireless terminal based on the Al agent system. For this, the wireless terminal recommends and reports many actions for the user on the basis of various events occurring in the wireless terminal. Accordingly, the user can use the terminal more effectively and enjoyably. On the basis of these events and the user's feedback action, the avatar quotient is varied.

The operation of the agent controller 130 with the above-described structure will be described with reference to FIG. 7. When an event is received from the event delivery server 120, the specialist manager 310 stores event information in an associated event storage area of the blackboard 330. At this time, the event information delivered from the event delivery server 120 has the format as shown in Table 1. When an event message as shown in Table 1 is received, the specialist manager 310 refers to the received event message and parameters, replaces the parameters with necessary information or further adds necessary parameters, and stores the event message and the necessary information in the blackboard 130. Then, the specialist manager 310 refers to the internal event-by-event specialist list, selects specialists associated with the received event from the specialists 322 to 328, and delivers the received event message. At this time, the specialists 322 to 328 are provided with an identifier (ID) of an avatar UI for agent expression when they are finally selected according to a necessary event and the supervisor 350.

At least two specialists may be mapped to one event. In this case, one specialist is selected such that a character UI can be expressed in accordance with an embodiment of the present invention. Also, at least two specialists are selected such that a character UI of each specialist can be expressed. When one specialist is selected to express a character UI, the specialist manager 310 requests that the supervisor 350 select the most suitable specialist. Then, the supervisor 350 analyzes data of the blackboard 330, a basically designated priority according to an event, and a user preference for the specialist, thereby selecting the most suitable specialist. When the supervisor 350 selects a specialist according to the received event, the specialist manager 310 sends, to the selected specialist, an avatar UI ID request for agent expression. When the UI ID is received from the specialist, the received ID is sent to the agent UI expression part 140.

When multiple specialists are selected to express a character UI, the specialist manager 310 notifies the supervisor 350 of specialists for expressing a character UI associated with an event. Then, the supervisor 350 refers to the priority allocation table as shown in Table 9, refers to a basically designated priority, and reflects a user preference for an associated specialist. Then, the supervisor 350 notifies the specialist manager 310 of a list of specialists arranged according to set priorities while performing the procedure. UI expression priorities of the specialists arranged as described above are stored in the priority queue as illustrated in FIG. 9. When the supervisor 350 selects specialists according to the received event, the specialist manager 310 sends, to an associated specialist, an avatar UI ID request for character UI expression according to the UI expression priorities of the selected specialists while identifying the priority queue. When the UI ID is received from the specialist, the received UI ID is sent to the agent UI expression part 140.

A procedure for selecting specialists associated with an event occurred as described above and expressing a character UI will be described. First, when an event (including an event collected by the event collector 110 or an event by a timer) is input, the specialist manager 310 identifies specialists registered for the input event from a list of event-by-event specialists and then notifies associated specialists of the input event. When the number of specialists associated with the input event is multiple, an inquiry is sent to the supervisor 350. Then, the supervisor 350 analyzes a designated priority and a user preference, sets UI expression priorities of specialists for expressing a character UI, orders the priorities, and notifies the specialist manager 310 of the ordered priorities. According to the ordering, the specialist manager 310 arranges the specialists in a priority buffer and performs a control operation to sequentially operate the specialists according to the ordered priorities and express a UI of an associated specialist.

According to the event occurrence and processing result in an embodiment of the present invention, a quotient of an avatar UI is changed and avatar growth is controlled. The avatar quotient can be changed when the specialists send a change request to the avatar quotient memory 340.

The agent UI expression part 140 receiving the above-described avatar UI ID has the structure as illustrated in FIG. 10. The agent UI expression part 140 manages a plurality of avatar UIs to be displayed to the user of the wireless terminal and performs an operation for displaying, to the user, an avatar UI mapped to a UI ID requested by the agent controller 130.

The wireless terminal with the character agent system uses a character as a UI. Here, it is assumed that the character is an avatar. Because the character UI is configured independent of the agent engine, the character UI can be used. Along with the character UI, various forms such as text, audio, and so on can be implemented. Table 10 shows a UI interface of the agent UI expression part 140. TABLE 10 <<abstract>> MagentExpression +SetFeedbackController (MAgentFeedback*aFeedbackController)( ) +Show (aUIId: TUIId. aSubIndex. ConstRTokens&): void +Hide ( )

The UI must be implemented with MAgentExpression as shown in Table 10. In Table 10, Show( ) is used to show a UI, and Hide( ) is used to hide a UI. The engine must designate a class to receive a feedback input for a UI through SetFeedbackController.

When the wireless terminal with an Al agent function uses a character UI in accordance with an embodiment of the present invention, the character can attract interest of the user using an avatar model. The avatar model can bring up the character according to use of the wireless terminal. In this case, the growth of the character (e.g., avatar) depends on time and use of the user's device. For example, the character is brought up as a period of time is elapsed. According to a method in which the user uses a device, a character quotient is variously changed and features of the character can be differently expressed.

Referring to FIG. 10, the agent UI expression part 140 is configured by an avatar UI manager 360 and a plurality of UIs 372 to 378 corresponding to avatar UIs. Here, the UIs 372 to 378 are avatar data to be actually displayed. The avatar UIs are avatars according to event avatar growth mode and steps of the mode and avatars set according to an avatar quotient.

Therefore, when the agent controller 130 receives an avatar UI ID, the avatar UI manager 360 selects a UI mapped to the avatar UI ID, and operates the avatar UI. The avatar UI is displayed on the display unit 27. In this case, the avatar UI can be displayed along with avatar UI text, voice, or music as well as an avatar UI image. When an event occurs, the user can identify an avatar image and text of an event according to the avatar growth mode and the avatar quotient in the avatar UI through the display unit 27.

When the user generates selection information after identifying an avatar UI displayed on the display unit 27, the avatar UI manager 360 is notified of an associated UI. The avatar UI manager 360 delivers the user feedback information to the agent controller 130.

The agent controller 130 with the structure as illustrated in FIG. 7 stores the user feedback information in the blackboard 330 and operates a specialist operating an associated UI. At this time, the user feedback information is an item selected by the user according to avatar UI text for the occurred event. For example, when contact information is not present after a message is received/transmitted in a message event, avatar UI text recommends that the user add contact information. Accordingly, response (yes/no) information made by the user is the user feedback information. When the user feedback information is generated as described above, the agent controller 130 delivers the user's feedback information to the specialist such that the specialist can process the feedback information. The avatar quotient can be changed through the specialist.

FIGS. 11 to 18 are flowcharts illustrating operation procedures of an avatar agent system of the wireless terminal with the structures as illustrated in FIGS. 4 to 10.

FIG. 11 is a flowchart illustrating a procedure for analyzing an event occurring in the avatar agent system as illustrated in FIG. 4 and operating the avatar agent system.

Referring to FIG. 11, the controller 100 collects an event and generates an event message when the event occurs in step 410. At this time, the generated event message has the structure as shown in Table 1. Then, the controller 100 delivers the occurred event to a device for processing the event in step 420. When the agent system has the structure as illustrated in FIG. 4, the device for processing the event may be the agent controller 130. When the device in which the event occurs is implemented only in the event collector 110, the event delivery server 120 can be omitted. In this case, the event can be directly delivered from the event collector 110 to the agent controller 130. Then, the controller 100 receives and analyzes the generated event message, selects a specialist for processing the event message from selected specialists, and sets a UI ID of the selected specialist in step 430. Then, the controller 100 selects an avatar UI mapped to the set UI ID from the avatar memory of the memory 23 and displays the selected avatar UI on the display unit 27 in step 440.

The displayed avatar UI may have a function for requesting the user's selection. Then, when the wireless terminal user selects an associated function, the controller 100 detects the selection in step 450 and then returns to step 430 to perform an agent control operation. At this time, the controller 100 repeats the above-described operation according to the user feedback information in step 430.

As described above, the wireless terminal can select an avatar UI mapped to the occurred event and display the event occurrence in the avatar agent function.

FIG. 12 is a flowchart illustrating an operation procedure of the event collector 110 in the agent system.

Referring to FIG. 12, the event collector 110 detects an event when the event occurs and processes the occurred event in step 511.

First, when a call event occurs, the event collector 110 detects the occurred call event in step 513 and processes the occurred call event in step 515. At this time, the call event detector 236 processes the call event. When the call event is detected, the event collector 110 processes the call event according to the procedure of FIG. 13.

Referring to FIG. 13, types of the call event may be an incoming call, an outgoing call, an answering call, a rejected call, a missed call, and so on. When the call event type is the incoming call, the event collector 110 stores incoming call information according to an incoming call time, a calling person, and so on in steps 551 and 553. When the call event type is the outgoing call, the event collector 110 stores outgoing call information according to an outgoing call time, a called person, and so on in steps 555 and 557. When the call event type is the answering call, the event collector 110 stores answering call information according to an answering time, a calling person, and so on in steps 559 and 561. When the call event type is the rejected call, the event collector 110 stores incoming call information according to a rejection time, a calling person, and so on in steps 563 and 565. When the call event type is the missed call, the event collector 110 stores missed call information according to a missed call time, a calling person, and so on in steps 551 and 553. When the event is not the above-described call event, the event collector 110 stores call duration time and subscriber information according to an associated call event in step 571. Then, the event collector 110 collects information according to a call event and generates an event message in step 573. Accordingly, when the call event detector 236 processes the procedure of FIG. 13, information of the detected call event is delivered to the event collection manager 210, such that an event message can be generated.

Second, when an alarm event occurs, the event collector 110 detects the occurred alarm event in step 517 and processes the occurred alarm event in step 519. At this time, the alarm event is processed in the schedule change event detector 230. When a schedule change event is detected, the event collector 110 processes the schedule change event according to the procedure of FIG. 14. Here, the term “schedule change event” includes a schedule, a schedule change, an alarm, and so on. In FIG. 14, the schedule change event will be described as the alarm event.

Referring to FIG. 14, the event collector 110 determines if the alarm event is an avatar alarm event when the alarm event occurs in step 581. If the alarm event is the avatar alarm event, the event collector 110 detects the avatar alarm event in step 581, stores alarm event information such as a type, time, and so on of the occurred alarm event in step 583, and collects information based on the avatar alarm event to generate an event message in step 587. However, if the alarm event is not the avatar alarm event in step 581, general alarm event information such as an alarm event type and time is stored and an event message is generated while steps 585 and 587 are performed. Accordingly, when the procedure of FIG. 14 is processed in the schedule change event detector 230, the detected alarm event information is delivered to the event collection manager 210, such that an event message can be generated.

Third, when a message event occurs, the event collector 110 detects the occurred message event in step 525 and processes the occurred message event in step 527. At this time, the message event is processed in the message event detector 228. When the message event is detected, the event collector 110 processes the message event according to the procedure of FIG. 15.

Referring to FIG. 15, message events are message reception, transmission, check, deletion, and so on. The above-described message events can occur in a short message service (SMS), multimedia messaging service (MMS), e-mail, and so on. When the message reception event occurs, the event collector 110 determines if the occurred message reception event is the SMS, extended message service (EMS), MMS, or e-mail event and stores a reception time and a message (e-mail) ID for the occurred event while performing steps 613 to 625. That is, when the message reception event occurs, the event collector 110 determines if the message reception event is the SMS, MMS, or e-mail event and stores a reception time and message (e-mail) ID of an analyzed message. The types of message events have been described as the SMS, EMS, MMS and e-mail in FIG. 15, but other messages as well as the three types of messages can be processed. In case of a type of a message event undefined in FIG. 15, an associated message event can be processed in step 625.

Then, the event collector 110 collects information of the message reception event such that an event message can be generated using the information in step 645. When the above-described procedure is processed in the message event detector 228, the detected message event information is delivered to the event collection manager 210 in step 645, such that the event message can be generated.

When the message transmission event occurs, the event collector 110 detects the occurred message transmission event in step 631 and determines if the message transmission event is the SMS, MMS, or e-mail event and stores a transmission time and message (e-mail) ID of an analyzed message in step 633. When the message check event occurs, the event collector 110 detects the occurred message check event in step 635 and determines if the message check event is the SMS, MMS, or e-mail event and stores a check time and subscriber information of an analyzed message in step 639. When the message deletion event occurs, the event collector 110 detects the occurred message deletion event in step 639 and determines if the message deletion event is the SMS, MMS, or e-mail event and stores a deletion time and message (e-mail) of an analyzed message in step 641. After the above-described operations are performed, the event collector 110 collects information of the message event such that an event message can be generated using the information in step 645. When the procedure of FIG. 15 is processed in the message event detector 228, the detected message event information is delivered to the event collection manager 210 in step 645, such that an event message can be generated.

Fourth, when an address book change event occurs, the event collector 110 detects the occurred address book change event in step 533 and processes the occurred address book change event in step 535. At this time, the address book change event is processed in the address book change event detector 228. When the address book change event is detected, the event collector 110 processes the address book change event according to the procedure of FIG. 16. Here, addresses may be a phone number, an address, an e-mail ID, and so on.

Referring to FIG. 16, the event collector 110 analyzes a type of the address book change event and stores an occurrence time and an address book change event item according to the analyzed type of the address book change event while performing steps 651 to 665 when the address book change event occurs. Here, the types of address book change events may be address addition, address edition, address deletion, and so on. According to the above-described address change event type, event information (of a time and item ID) is stored. The types of address book change events have been described as the address addition, address edition, address deletion, and so on in FIG. 15, but other address book changes as well as the three types of address book changes can exist. When a different address book change event rather than the three types of address book changes occurs, the event collector 110 stores information of an associated address book change event in step 663. After the above-described operations are performed, the event collector 110 collects information of the address book change event such that an event message can be generated using the information in step 665. When the procedure of FIG. 16 is processed in the address book event detector 224, the detected address book event information is delivered to the event collection manager 210 in step 665, such that an event message can be generated.

In the above-described method, other events such as a system event, a setup change event, a camera event, and a broadcast event are processed. After the events are processed, the event collector 110 generates an event message using information of the processed event in step 547. At this time, the event message has the structure as shown in Table 1. The generated event message is delivered to the event delivery server 120 or the agent controller 130 in step 549.

FIG. 17 is a flowchart illustrating a procedure for delivering a received event from the event delivery server 120 of the agent system.

Referring to FIG. 17, the event delivery server 120 performs an initialization operation in step 671. When a message is received, the event delivery server 120 detects the received message in step 673 and determines if the message is a message for requesting event message delivery or a generated event message in steps 675 and 681. Here, the message for requesting event message delivery is generated from the agent controller 130, and the event message is generated from the event collector 110. When the message is the event delivery request message, the event delivery server 120 detects the request message in step 675 and registers a client connector (i.e., the second client connector 254 in accordance with an embodiment of the present invention) for delivering the event message in step 679. That is, the second client connector 254 is registered such that the received event message can be delivered to the agent controller 130. When the received message is the event message, the event delivery server 120 detects the received event message in step 681 and delivers the received event message (i.e., the event message generated from the event collector 100 or the application message) through the client connector (i.e., the second client connector 254) requesting the event delivery. When a message is not the event request or received event message, an associated message is processed as an error in step 683.

As described above, the event delivery server 120 performs a function for delivering event messages generated from the event collector 110 and other application events to the agent controller 130 making an event delivery request. When an agent control operation is not performed for the application events, the event delivery server 120 can be omitted.

FIGS. 18 and 19 are flowcharts illustrating an agent control procedure according to an event message delivered from the agent controller 13 of the agent system. Here, FIG. 18 illustrates the procedure for identifying specialists expressing character UIs for an occurred event when the event occurs, selecting a specialist with the highest designated priority and user preference from the specialists, and expressing a UI ID of the selected specialist. Also, FIG. 19 illustrates the procedure for identifying specialists expressing character UIs for an occurred event when the event occurs, identifying designated priorities and user preferences for the specialists, setting and arranging UI expression priorities in order of specialists with high UI expression priorities and user preferences, and expressing UI IDs of associated specialists according to the arranged UI expression priorities.

First, referring to FIG. 18, the agent controller 130 waits an event message to be received in step 711. When the event message is received, necessary information according to the received event is collected and stored in the blackboard 330. At this time, the event information stored in the blackboard 330 can have the format of Table 1. After the event information is stored in the blackboard 330, the agent controller 130 identifies specialists registered in an event-by-event specialist list associated with the occurred event and asks the identified specialists about the presence of an associated case in step 715. That is, the agent controller 130 selects specialists for processing the occurred event, and asks the selected specialists about an associated case for the occurred event among use cases as shown in Table 4. When at least two specialists are present for the occurred event case, the agent controller 130 allows the supervisor 350 to select the most suitable specialist from the specialists associated with the event. When selecting a specialist mapped to the occurred event, the supervisor 350 analyzes content of the blackboard, a designated priority, and a user preference and selects the specialist. When the supervisor 350 selects one specialist, the agent controller 130 detects the selected specialist in step 719 and then obtains an avatar UI ID of the selected specialist in step 721.

In this process, associated specialists can suitably change an avatar quotient. The avatar quotient is preset which is mapped to each event. When the avatar quotient mapped to each event must be changed, an associated specialist changes the avatar quotient through the avatar quotient memory 340.

Then, the agent controller 130 delivers an avatar UI ID obtained from the selected specialist to the agent UI expression part 140 and then waits the user feedback information to be received in step 721. Then, the agent UI expression part 140 operates a UI mapped to the avatar UI ID and performs avatar agent expression according to the occurred event. At this time, the UI is provided with an avatar according to avatar growth mode of each event and a step in the growth mode and avatar information set for the avatar quotient. This avatar information is displayed on the display unit 27. The avatar information displayed on the display unit 27 may be an image and text for the avatar UI. Then, the user can make a response while viewing the image and text based on the avatar UI displayed on the display unit 27. Response information of the user is user feedback information. The agent UI expression part 140 delivers the user feedback information to the agent controller 130.

When the user feedback information is received from the agent UI expression part 140, the agent controller 130 delivers the user feedback information to an associated specialist and requests that the specialist perform an operation according to the user feedback information. The associated specialist can suitably change an avatar quotient according to the feedback information. The agent controller 130 stores the user feedback information in the blackboard 330 in step 733. Then, the event control procedure proceeds to step 711.

Second, referring to FIG. 19, the agent controller 130 waits an event message to be received in step 751. When the event message is received, necessary information according to the received event is collected and stored in the blackboard 330 in step 753. At this time, the event information stored in the blackboard 330 can have the format of Table 1. After the event information is stored in the blackboard 330, the agent controller 130 identifies a character quotient of the occurred event and then changes the character quotient stored in the avatar quotient memory 340 in step 755. Then, the agent controller 130 asks specialists, registered in an event-by-event specialist list of the specialist manager 310, about an associated case for the occurred event in step 757. Then, the agent controller 130 computes UI expression priorities of specialist candidates for character UI expression according to a result of the asking through the supervisor 350, arranges suitable specialist candidates while considering UI expression priorities according to a result of the computation, excludes unsuitable specialist candidates, and stores and queues the specialists for performing the character UI expression in the priority queue as illustrated in FIG. 9 in step 761. The principle and method for setting a UI expression priority of the specialist in the supervisor 350 has been described above.

Then, the agent controller 130 determines if a character UI currently being displayed on the display unit 27 is present in step 763. If the character UI is currently being displayed, processing can be made according to a priority of a specialist stored in the priority queue. As described above, the character UI expression of a specialist with UI Expression Priority 0 is immediately performed regardless of the current display state. The specialists of UI Expression Priorities 1 and 2 wait for character expression while the character expression of a different specialist is performed. When the specialist of UI Expression Priority 0 is present among the specialists stored in the priority queue, the agent controller 130 stops the current character UI expression in step 765. However, when the specialist of UI Expression Priority 0 is not present among the specialists stored in the priority queue, the agent controller 130 can wait until the current character UI expression is completed in step 765. When a new event occurs and specialists for performing character expression are set, the agent controller 130 can stop the character UI expression currently being displayed and express character UIs of the specialists set by the event. In this case, the agent controller 130 can stop the current character UI expression in step 765.

When a character UI currently being expressed is absent in step 763 or after step 765 is performed, the agent controller 130 accesses a UI ID of a specialist with the highest UI expression priority among the specialists stored in the priority queue in step 767 and performs a control operation such that a character UI of an associated specialist is expressed through the agent UI expression part 140 in step 769. The specialist having expressed the character UI is removed from the queue. Then, a character UI of an associated specialist is displayed on the display unit 27. At this time, the displayed character UI may and may not require the user's feedback. When the user issues a feedback command in a state in which the character UI requiring the user's feedback is expressed, the agent UI expression part 140 delivers the feedback command to the agent controller 130. The agent controller 130 detects the feedback command in step 771, controls the character UI currently being expressed to be stopped in step 773, stores user feedback information in the blackboard 330 in step 775, and requests that the specialist expressing the character UI act according to a result of the user feedback in step 777. At this time, the specialist is provided with a UI ID for taking action according to the result of the user's feedback (i.e., the result of the positive or negative feedback). The agent controller 130 delivers the UI ID mapped to the action of the specialist to the agent UI expression part 140 and performs a control operation such that a character UI is expressed. The agent controller 130 identifies a character quotient according to the feedback result, and performs a control operation such that an associated character quotient is updated in the avatar quotient memory 340 in step 779.

However, if the UI does not require the user feedback or the user feedback is not received within the set time in step 771, or after step 779 is performed, the agent controller 130 determines if specialists waiting in the priority queue are present in step 781. If the specialists waiting in the priority queue are present, the agent controller 130 accesses a UI ID of a specialist with the next UI expression priority among the specialists waiting in the queue in step 783 and then proceeds to step 769 to express a character UI according to the above-described procedure. As described above, the specialist having expressed the character UI is removed from the priority queue.

When the above-described operation is repeated, character UIs of the specialists waiting in the priority queue can be sequentially expressed according to UI expression priorities. When character UI expressions of all the specialists waiting in the priority queue are completed, the agent controller 130 detects the expression completion, stops the procedure for controlling the character UI expression operation, and waits the next event to be received in step 781.

When an event occurs as described above, the agent controller 130 asks the specialists, registered in a list of event-by-event specialists, about the expression possibility of a character UI, and can perform a process in two methods when at least specialists can express character UIs. That is, one specialist capable of expressing the most suitable character UI is selected from many specialists through the supervisor 350 as illustrated in FIG. 18, such that the character UI can be expressed. Alternatively, as illustrated in FIG. 19, multiple specialists capable of expressing characters through the supervisor 350 are selected, character UI expression priorities of the selected specialists are set, and character UIs can be sequentially expressed according to the UI expression priorities. When the character UI is expressed, a character quotient mapped to the occurred event is changed. When the specialist expresses a user feedback UI, a character quotient is changed according to the user's feedback. Here, the character quotient can be used for character growth and/or state expression.

The above-described agent system uses a timer in a method for operating a specialist. That is, types of occurred events are an event in which an avatar UI must be immediately expressed and an event in which an avatar UI must be expressed at a specific time. For example, when an event associated with a call, a message and so on occurs and an avatar UI is expressed, the selected specialist is operated at an event occurrence time. However, when an event must be operated at a specific time as in an alarm event and so on, the specialist must be operated at the specific time. The specialist to be operated at a specific time requests that the specialist manager 310 wake it up at the specific time. When the specific time is reached, the specialist manager 310 operates an associated specialist. At this time, the agent controller 130 uses the single timer processor 370 to reduce the system load. The specialist manager 310 stores a request for what is a sequence number of a specialist to be woke up at a time (year, month, hour, minute, second, etc.) in the blackboard 370, and performs a setup operation only for the earliest request of stored requests in the timer processor 370. When the set time is reached, an associated event is processed. After an associated request is deleted from the blackboard 330, a time for the next earliest request is set in the timer processor 370. The specialist synthetically considers the blackboard 330 and many situations even when a time is reached, determines whether to operate, and notifies the specialist manager 310 of a result of the determination. When an associated specialist determines to operate, it performs the remaining processes like specialists for other events (i.e., specialists operating at an event occurrence time). When a time set in the timer processor 370 is deleted or changed, the specialists are responsible for these operations. That is, when a function of the timer processor 370 is unnecessary in state in which the function is reserved to process an event, an associated specialist must perform an operation for deleting or changing a reservation time to use the timer processor 370.

Table 5 shows concrete cases in accordance with an embodiment of the present invention. Table 5 shows event use cases, case classification, event determination times, action (processing) times of specialists, the number of occurrences, times, event parameters (necessary information), conditions, UI text, user options, and so on. Other cases can be added to the above cases or some cases can be deleted.

When an agent alarm service is performed, it can be divided into various types according to a use case of an event. As shown in the class item of Table 5, a message, mail, digital broadcasting, GPS, camera multimedia, system, avatar, schedule, call, call/message event, To Do, and application events can be classified and provided. The use cases as shown in Table 5 are referred to according to characteristics of the events and four types of use cases can be classified and provided. Now, the four types of the use cases will be described. An operation for processing an event message according to the event classification of Table 5 will be described in more detail. The types will be described on the basis of Case IDs 1 to 50, and a description of other types is omitted.

First, Case IDs 1 to 50 of Table 5 classified according to the four types, i.e., A to D types, will be described.

First, A-type cases are of Case IDs 12, 14, 46, 47, 25, 11, 13, 29 and 30 in Table 5. A procedure for processing the A-type cases will be described. First, when an event occurs, an associated detector of the event collector 110 detects the occurred event and the event collector 110 generates an event message mapped to the occurred event and sends the generated event message to the event delivery server 120. Then, the specialist manager 310 of the event controller 130 stores the event message in the blackboard 330, refers to a specialist list mapped to the event, and delivers the event to associated specialists. Then, the specialists check an associated condition. Then, if the condition is satisfied, the specialists sends a timer setup request to the specialist manager 310.

When a timer event occurs after the above-described operation is performed, the agent controller 130 calls a specialist ID for the timer event and therefore the specialist re-checks the condition. When the condition is not satisfied, the operation ends. When the condition is satisfied, the agent controller 130 sends the ID to the supervisor 350 and performs a control operation such that agent event expression can be performed.

Second, B-type cases are of Case IDs 15, 16, 50, 17, 18, 31, 32, 35, 36, 37, 2, 3, 9, 4, 5, 6, 38, and 41 in Table 5. A procedure for processing the B-type cases will be described. First, when an event occurs, an associated detector of the event collector 110 detects the occurred event and the event collector 110 generates an event message mapped to the occurred event and sends the generated event message to the event delivery server 120. Then, the specialist manager 310 of the event controller 130 stores the event message in the blackboard 330, refers to a specialist list mapped to the event, and delivers the event to associated specialists. Then, the specialists check an associated condition. If the condition is not satisfied, the specialists end the operation without making any response or with returning NO. If the condition is satisfied, the specialists make a response or return YES.

After the above-described operation is performed, specialists for performing character UI expression are selected through competition (based on a designated priority, and a blackboard avatar state (or a user preference)) between the specialists making a response (or returning YES), such that UIs of the selected specialists are expressed. Here, the specialists for expressing the character UIs can be selected using the above-described two methods. That is, the supervisor 350 of the agent controller 130 analyzes the specialists making the response and selects a specialist that has the highest relation to the occurred event as illustrated in FIG. 18. The specialist manager 310 obtains a UI ID of the specialist selected by the supervisor 350 and outputs the obtained UI ID to the agent UI expression part 140. As illustrated in FIG. 19, the supervisor 350 analyzes designated priorities and user preferences for the specialists making the response, sets and arranges UI expression priorities of the specialists according to a result of the analysis, sequentially obtains UI IDs of associated specialists according to the arranged UI expression priorities, and outputs the obtained UI IDs to the agent UI expression part 140. Then, the agent UI expression part 140 selects a UI mapped to a UI ID and displays an avatar UI.

Third, C-type cases are of Case IDs 1, 42, 43, 48, 50, 7, 8, 10, 33, 34, 44, 45, 21, 27, 28, 49, 39, and 40 in Table 5. The C-type specialist ID repeats every N days. Here, Case IDs 1, 42, 43, 48, 50, 7, 8, 10, 33, 34, 44, and 45 require a condition, while Case IDs 21, 27, 28, 49, 39 and 40 do require a condition.

Accordingly, when a preset timer event occurs after N days are elapsed, the agent controller 130 calls a specialist of an alarm event mapped to each event ID. An associated specialist determines if a condition is satisfied. If the condition is satisfied, a specialist UI is delivered to the agent UI expression part 140, such that agent event expression is performed. However, if the condition is not satisfied, the operation ends.

Fourth, D-type cases are of Case IDs 19, 20, 23, 24, and 26 in Table 5. When a holiday is first added, an anniversary is added to a calendar, or a meeting schedule is registered, a timer is set. The timer registration for a holiday and an anniversary may occur before one week and before one day. In case of the meeting, a timer can be set for meeting schedule start and end times, etc.

When a D-type case occurs, the agent controller 130 calls a specialist of the timer event mapped to each case ID. An associated specialist checks a condition (or a time set for a holiday, anniversary, and meeting). If the condition is not satisfied, the operation ends. However, if the condition is satisfied, the agent controller 130 delivers a UI of an associated specialist to the agent UI expression part 140 and performs a control operation such that agent event expression can be performed.

In accordance with the above-described embodiment of the present invention, events are classified on a use case-by-use case basis and a timer is registered. When the timer occurs, a specialist mapped to an associated timer is operated. In an embodiment of the present invention, the first type (A type) is the type for processing events not requiring the user feedback. When an alarm event is set for event occurrence in a specific state of the wireless terminal and an associated state occurs, an event is processed in an avatar agent alarm. Second, the second type (B type) is the type for processing events requiring the user feedback. When an event occurs, specialists satisfying the condition among specialists associated with the event make a response. A specialist of the highest priority is selected from the specialists making the response, and an avatar UI of the selected specialist is expressed. Third, the third type (C type) is associated with events repeating in a predetermined period. Set alarm information is identified and avatar agent expression is performed on a set day. Fourth, the fourth type (D type) is associated with alarm events according to a schedule set by the user. When a set date or time is reached, an avatar agent is expressed.

Second, an operation according to the type of Table 5 will be concretely described. Here, mail, system, schedule, call, call/message, and application events will be concretely described. In the following description, FIGS. 20 to 25 illustrate procedures for processing occurred events according to use cases in an embodiment of the present invention. FIGS. 26A to 32 illustrate examples of displaying character UIs according to a set UI ID while processing the procedures of FIGS. 20 to 25. In the following description, an example in which a specialist with the highest UI expression priority is selected from the specialists associated with each event in the supervisor 350 of the agent controller 130 and character UI expression is performed will be described. When multiple specialists perform the character UI expression according to an event as illustrated in FIG. 19, the supervisor 350 sets UI expression priorities of the specialists for expressing character UIs, waits after arranging the specialists according to the set UI expression priorities, and sequentially identifies UI IDs of the specialists according to the UI expression priorities, and allows a character UI to be displayed.

Processing order when the e-mail event occurs will be described. FIG. 20 illustrates a procedure for processing an e-mail reception event.

Referring to FIG. 20, the event collector 110 collects an e-mail reception event if the event occurs at the time of receiving e-mail in step 802 and provides the collected event to the event delivery server 120 in step 804. The event delivery server 120 delivers the event to the specialist manager 310 of the agent controller 130 in step 806. Then, the specialist manager 310 stores the received e-mail reception event in the blackboard 330 in step 808, identifies specialists to be called from a list of event-by-event specialists of the specialist manager 310 in step 810, and calls specialists associated with the e-mail reception event in step 812. As shown in Table 5, specialists associated with an e-mail event are of IDs 17, 18, and 47 to process the event. In FIG. 20, it is assumed that the specialists of IDs 17, 18, and 47 are called.

Among the called specialists, a use case of ID 17 is associated with an event of a case capable of being ignored or deleted when a received e-mail is not read. Accordingly, the specialist of ID 17 determines if the received e-mail has been continuously ignored in step 814. The determination as to whether the received e-mail has been continuously ignored is made by comparing the name, address, title, or e-mail content of an e-mail sender with associated items of a previously stored received e-mail. When an identical item is present, the received e-mail is regarded as the e-mail capable of being ignored or deleted. When an identical e-mail has been successively ignored or deleted a user set number of times or more (e.g., three or more times), it is regarded that an associated e-mail has been continuously ignored. When the associated e-mail has not been continuously ignored as a result of the determination, the specialist (of ID 17) proceeds to step 815 to return ‘NO’ to the specialist manager 310. On the other hand, when the associated e-mail has been continuously ignored, the specialist of D17 proceeds to step 816 to return ‘YES’ to the specialist manager 310.

Among the called specialists, the specialist of ID 18 determines if a received e-mail is a spam mail in step 820. A criterion of the determination as to whether the received e-mail is the spam depends on a conventional spam mail designation method. When the sender name, address, title or e-mail content of a received e-mail among received e-mails is equal to that of an e-mail classified as the spam mail according to a setup operation of the user, the received e-mail can be regarded as the spam mail. When a specific sentence or word set by the user to detect the spam mail is contained in the sender name, address, title, or e-mail content of a received e-mail, the received e-mail can be regarded as the spam mail. When the received e-mail is not the spam mail in the above-described method, the specialist of ID 18 proceeds to step 821 to return ‘NO’ to the specialist manager 310. On the other hand, when the associated e-mail is the spam mail, the specialist of D18 proceeds to step 822 to classify the associated e-mail as the spam mail and then proceeds to step 823 to return ‘YES’ to the specialist manager 310.

Among the called specialists, the specialist of ID 47 determines if the number of unread e-mails of an inbox is equal to or more than a preset reference value and determines if there are many unread e-mails in step 830. If there are not many unread e-mails as a result of the determination, the specialist of ID 47 proceeds to step 831 to return ‘NO’ to the specialist manager 310. On the other hand, if there are many unread e-mails, the specialist of ID 47 proceeds to step 832 to set a suitable alarm (of Alarm ID 47 for convenience) and then proceeds to step 833 to return ‘NO’ to the specialist manager 310.

When the called specialists (e.g., the specialists of IDs 17, 18, and 47) make the return, the specialist manager 310 provides the supervisor 350 with specialist IDs returning ‘YES’ (e.g., Specialist IDs 17 and 18 of FIG. 20) in step 840. Then, the supervisor 350 identifies UI expression priorities of associated specialists (e.g., specialists of IDs 17 and 18) or identifies the execution of an associated specialist to set the specialist of the highest UI expression priority when the number of specialists returning ‘YES’ is one in step 842. In step 844, the supervisor 350 sends, to the specialist manager 310, a result of the identification for the highest priority specialist or the execution of the associated specialist. Then, the specialist manager 310 identifies a preset UI ID according to each ID of the highest priority specialist or the specialist to be executed in step 846 and sends the identified UI ID to the agent UI expression part 140 in step 848. In step 850, the agent UI expression part 140 expresses an associated UI on the display unit 27 and reproduces an associated audio signal through the audio processor 27 if needed.

The UI expression of the agent UI expression part 140 displays text mapped to an associated UI ID as shown in text examples of Table 5 as well as an avatar image mapped to a UI ID of the set specialist. For example, when the UI expression mapped to the specialist of ID 17 is made, content asking if a received e-mail previously ignored must be again ignored can be included. When the UI expression mapped to the specialist of ID 18 is made, content asking if a received spam mail must be deleted can be included. Then, when the user identifies the UI image and text displayed on the display unit 27 and makes a response (e.g., YES or NO), the agent UI expression part 140 provides user feedback information to the agent controller 130. The agent controller 130 operates the specialist of an associated ID according to the user feedback information and delivers a UI ID to the agent UI expression part 140 such that a UI can be expressed according to the user feedback information. Accordingly, the agent UI expression part 140 displays the UI image and text based on the user's feedback on the display unit 27.

FIG. 21 illustrates an operation procedure at the time of processing a call/message event in accordance with an embodiment of the present invention. FIG. 21 is a flowchart illustrating a procedure for processing call end, transmission, and message read events among call events.

Referring to FIG. 21, the event collector 110 collects an event when the event occurs in step 902 and provides the collected event to the event delivery server 120. The event delivery server 120 provides the event to the specialist manager 310 of the agent controller 130 in step 906. Then, the specialist manager 310 stores the received event in the blackboard 330 in step 908, identifies specialists to be called according to the event from an internal specialist list in step 910, and calls the identified specialists in step 912. It is assumed that the specialists of IDs 4, 5, and 6 as shown in Table 5 are registered in the internal specialist list of the specialist manager 310 such that they are called when the event occurs.

Among the called specialists, the specialist of ID 4 makes a recommendation for setting a relation to a specific person frequently making contact with the user during several recent days when the relation is not set. The specialist of ID 4 identifies an event stored in the blackboard 330 and identifies a communicator ending a call, a receiver of a sent message, or a sender reading the message. The specialist determines if the user has communicated with a communicator (i.e., a sender/receiver) a preset number of times or more (e.g., five or more times for call or message transmission and reception) during one recent week. The specialist determines if a relation is set to a specific person (i.e., a communicator/sender/receiver) often making contact with the user. If the relation is set as a result of the determination, the specialist of ID 4 proceeds to step 915 to return ‘NO’ to the specialist manager 310. If the relation is set as a result of the determination, the specialist proceeds to step 916 to return ‘YES’ to the specialist manager 310. When ‘YES’ is returned in step 916, the specialist of ID 4 can send information about a specific person of the event to the specialist manager 310.

Among the called specialists, the specialist of ID 5 is a specialist for making the praise if the relation to the specific person is set. The specialist of ID 5 identifies information stored in the blackboard 330 and identifies a communicator ending a call, a receiver of a sent message, or a sender reading the message in step 920. Then, the specialist of ID 5 determines if the user has made contact with a communicator (i.e., a sender/receiver) a preset number of times or more (e.g., five or more times for call or message transmission and reception) during one recent week. The specialist determines if a relation is set to a specific person (i.e., a communicator/sender/receiver) often making contact with the user. If the relation is not set as a result of the determination, the specialist of ID 5 proceeds to step 921 to return ‘NO’ to the specialist manager 310. If the relation is set as a result of the determination, the specialist proceeds to step 923 to return ‘YES’ to the specialist manager 310. When ‘YES’ is returned in step 923, the specialist of ID 5 can send information about a specific person of the event to the specialist manager 310.

Among the called specialists, the specialist of ID 6 is a specialist for making a relation setup recommendation if a relation is not set to a specific person continuously making contact with the user during several recent weeks. The specialist of ID 6 identifies event information stored in the blackboard 330 and identifies a communicator ending a call, a receiver of a sent message, or a sender reading the message in step 930. Then, the specialist of ID 6 determines if the user has continuously made contact with an associated communicator (i.e., a sender/receiver) during one recent month. The determination as to whether continuous contact during one month has been made can be made by determining if the user communicated with the specific person (through a phone call/message exchange) three or four weeks ago and again communicated with the specific person one week ago. The specialist determines if the relation is set to the specific person with whom the user has made continuous contact. If the relation is set as a result of the determination, the specialist proceeds to step 931 to return ‘NO’ to the specialist manager 310. If the relation is set as a result of the determination, the specialist proceeds to step 933 to return ‘YES’ to the specialist manager 310. When ‘YES’ is returned in step 933, the specialist of ID 6 can send information about a specific person of the event to the specialist manager 310.

When the called specialists make the return, the specialist manager 310 provides the supervisor 350 with the ID (e.g., ID 4, 5, or 6 in FIG. 21) of a specialist returning ‘YES’ in step 940. Then, the supervisor 350 identifies UI expression priorities of associated specialists (e.g., specialists of IDs 17 and 18) or identifies the execution of an associated specialist to set the specialist of the highest UI expression priority when the number of specialists returning ‘YES’ is one in step 942. In step 944, the supervisor 350 sends, to the specialist manager 310, a result of the identification for the highest priority specialist or the execution of the associated specialist. Then, the specialist manager 310 identifies a preset UI ID according to each ID of the highest priority specialist or the specialist to be executed in step 946 and sends the identified UI ID to the agent UI expression part 140 in step 948. In step 950, the agent UI expression part 140 expresses an associated UI on the display unit 27 and reproduces an associated audio signal through the audio processor 27 if needed.

The UI expression of the agent UI expression part 140 displays text mapped to an associated UI ID as shown in text examples of Table 5 as well as an avatar image mapped to a UI ID of the set specialist.

At this time, the specialist manager 310 sends information about a specific person when sending a UI ID associated with the specialist of ID 4 or 6 to the agent UI expression part 140, such that the agent UI expression part 140 expresses content for recommending the relation setup as well as information about the specific person when making the UI expression. The information about the specific person is sent simultaneously when the UI ID associated with Specialist ID 5 is sent, such that the agent UI expression part 140 expresses content for making the praise when the number of calls/messages is large as well as the information about the specific person at the time of the UI expression.

When a UI for recommending the relation setup is expressed, the display unit 27 can include content for asking if the user wants to set up the relation. Then, the user identifies a UI image and text displayed on the display unit 27. When the user makes a response (e.g., YES or NO), the agent UI expression part 140 provides the user feedback information to the agent controller 130. Then, the agent controller 130 operates the specialist of an associated ID according to user feedback information and delivers a UI ID to the agent UI expression part 140 such that a UI can be expressed according to the user feedback information. Accordingly, the agent UI expression part 140 displays the UI image and text based on the user's feedback on the display unit 27.

As described above, the event collector 110 collects events occurring in the wireless terminal. The agent controller 130 selects an optimal or highest priority specialist associated with the collected event and provides a UI ID of the selected specialist to the agent UI expression part 140. The agent UI expression part 140 displays a character image and/or text data mapped to the provided UI ID on the display unit 27. A UI displayed on the display unit 27 may be data requiring the user feedback information. When the user feedback information is generated, the agent UI expression part 140 provides the feedback information to the agent controller 130. Then, the agent controller 130 sets a UI ID according to the provided feedback information and then provides the set UI ID to the agent UI expression part 140.
